ABSTRACT:

SUMMARY OF THE INVENTION
The object of the invention is to develop a wheel bearing of the above type in such a way that there is a relatively simple connection and transmission of torque between the brake disk or drum and the wheel bearing, and wherein little weight is required in the elements to effect that connection.
The invention concerns a wheel bearing in particular for a motor vehicle wherein the wheel bearing has a central hub, a wheel flange around the hub, and at least one roller bearing between them. The roller bearing may be connected with or integrated with the wheel flange. A brake drum or brake disk may be detachably fastened to the wheel flange.
The wheel flange around the outer raceway has a periphery with a positive locking receptacle for receiving a brake drum or brake disk thereat, and the brake disk or brake drum has a shape for cooperating with the positive locking receptacle on the wheel flange, such that torque is transmitted between the brake disk or drum and the wheel flange at the positive locking receptacle.
The wheel flange has a positive locking connection formed thereon, for example the flange may have a polygon or polyhedron shaped periphery, e.g. an octagon shape. The brake drum or brake disk has an opening therein to cooperate with the shape of the exterior of the wheel flange for transmitting torque from the brake disk or drum to the flange. There are appropriate fastening means for the brake disk or the brake drum on the wheel flange. Those fastening means may comprise bolts that pass through appropriate threaded holes.
Other features and advantages of the present invention will become apparent from the following description of an exemplary embodiment of the invention which refers to the accompanying drawings.
